Fixed Resource Allocation Method and Device in a Broadband Wireless Communication System

1. A method for receiving, by a terminal, a data packet via a persistently allocated resource, the method comprising: receiving a persistent resource allocation message having a persistent allocation period and frame offset information from a base station; and receiving a frame having a data packet on the persistently allocated resource, non-periodically with respect to the persistent allocation period, wherein a non-periodical reception timing of the frame is computed based on the frame offset information which indicates a number of frames between the frame and a predetermined frame position.

2. The method of claim 1 , wherein the predetermined frame position is a position of an initial frame for a persistent resource allocation.

3. The method of claim 1 , wherein the predetermined frame position is located after the persistent allocation period from an initial frame for a persistent resource allocation.

4. The method of claim 1 , wherein the frame offset varies according to a number of retransmissions of the persistent resource allocation message from the base station.

5. The method of claim 4 , further comprising: computing the non-periodical reception timing of the frame using the frame offset information.

6. The method of claim 1 , wherein the non-periodical reception timing of the frame is earlier than a timing according to the persistent allocation period.

7. The method of claim 1 , wherein the persistent resource allocation message is received via an initial frame for a persistent resource allocation and the received frame is a second frame for the persistent resource allocation.

8. The method of claim 1 , further comprising: receiving a third frame for a persistent resource allocation periodically according to the persistent allocation period.

9. The method of claim 8 , wherein the third frame is received without frame latency, regardless of whether the persistent resource allocation message has been received by a retransmission process.

10. A device in a terminal in a broadband wireless communication system in which a persistent allocation technique is employed, the device comprising: a receiving unit configured to receive a persistent resource allocation message having a persistent allocation period and frame offset information from a base station; and a processor configured to control the receiving unit to receive a frame non-periodically with respect to the persistent allocation period, wherein a non-periodical reception timing of the frame is computed based on the frame offset information which indicates a number of frames between the frame and a predetermined frame position.

11. The device of claim 10 , wherein the predetermined frame position is a position of an initial frame for a persistent resource allocation.

12. The method of claim 10 , wherein the predetermined frame position is located after the persistent allocation period from an initial frame for a persistent resource allocation.
